MIT AND TOYOTA RELEASE DATASET FOR
AUTONOMOUS DRIVING RESEARCH

MODULATING LIGHT FOR BETTER LIDAR
SENSORS

How can self-driving vehicles be
trained to have a deeper awareness
of the world around them? That is
one of the questions researchers
from the Massachusetts Institute
for Technology (MIT) AgeLab at
the MIT Center for Transportation
& Logistics and the Toyota
Collaborative Safety Research
Center (CSRC) are trying to answer
by sharing an innovative new

to encourage researchers, the
industry, and other innovators to develop new insight and direction into
temporal AI modeling that enables the next generation of assisted driving
and automotive safety technologies. To date, self-driving data made
available to the research community have primarily consisted of troves
of static, single images that can be used to identify and track common
objects found in and around the road-such as bicycles, pedestrians, or
traffic lights-through the use of "bounding boxes." By contrast, DriveSeg
contains more precise, pixel-level representations of many of these same
common road objects, but through the lens of a continuous video driving
scene. This type of full scene segmentation can be particularly helpful for
identifying more amorphous objects.

The autonomous vehicle
industry is exploring "frequency
modulated continuous wave"
(FMCW) lidar to address the
challenge of distinguishing
between types of objects-
such as a child versus a
brown bag. Researchers at

project will provide a
total of $32.8 million to
the five teams during the next four years. Unlike other
NASA-funded research programs in which the agency
specifies the project goals, universities are asked to
come up with a compelling investigation, so long as
that technical challenge addresses one of the strategic
research thrusts of NASA. Another key goal of ULI is for
the student researchers involved to gain experience in
leading a multidisciplinary team made up of partners
from other universities and industry, especially

their skills to aviation problems. Receiving funds will be

will also decrease the
aircraft's performance during takeoff and landing. Engineers from
Rensselaer Polytechnic Institute are using their knowledge of flow
physics to determine how airflow will affect these new jet fighters and
how that flow can be manipulated or changed for optimal operation.
"During takeoff, the nose of the new aircraft can go up and experience
stall. So we want to control the flow of air so that doesn't happen,"
said Miki Amitay, an Endowed Professor of mechanical, aerospace, and
nuclear engineering at Rensselaer and the Director of the Center for
Flow Physics and Control (CeFPaC).
